Sōzu is a fast, always-up HTTP and TCP reverse proxy written in Rust that can be reconfigured at runtime without reloads and upgrades itself while still processing requests. It uses a share-nothing worker architecture with epoll event loops, terminates TLS via pluggable crypto backends, and exposes a control-plane socket plus an optional live TUI dashboard.

Use cases

• terminate TLS in front of backend servers
• reconfigure proxy routing without downtime or reloads
• upgrade the proxy binary while connections stay alive
• shield and load-balance backends in a PaaS or cloud platform
• run a memory-safe reverse proxy for high-traffic infrastructure
• monitor proxy traffic live from the terminal with sozu top

When to choose

• you need zero-downtime configuration changes and binary upgrades
• you run a dynamic platform with frequent deployments and want an always-up proxy
• you want a Rust-based, memory-safe alternative to HAProxy or nginx for HTTP/TCP proxying
• you need a control-plane-driven proxy with atomic config diffs over a unix socket

When to avoid

• you need a full-featured web server with scripting, caching, or static file serving
• you require non-Linux production platforms (prebuilt binaries target Linux only)
• you need a proxy with a large plugin ecosystem or extensive community modules
• AGPL-3.0 licensing is incompatible with your product plans
